Introduction: Toner Transfer Material Print Tests

This summer I was testing which printable materials best do iron-on toner transferring(to PCB's), here are the initial print results. I never really got anywhere because when I tried to transfer test 6, I warped the hell out of the board and the paper refused to ultimately release (I used an iron I modified the thermal switch on).
Tests 1-4 were on waxed cooking paper.
Tests 5 and 6 were on "regular" printer paper.
